How to get another three stars in angry birds space world 1 level 29
Its the second to last level of pig bang in angry birds space, and its a hard one. Fire the first bird as seen in the screenshot. When the bird reaches about the point of the first bird press your screen on the other side of the lower rightmost crate of TNT. The crate will blow and send debris all over the place, taking out several pigs and maybe some more crates. If you are lucky all you are left with is the pig behind the brick wall. If you are not restart the level and try again until you are there. Now fire the second bird into the crate in the wall on the far right side.
